ExamPrep NG is a live AI-powered exam preparation platform built for Nigerian students preparing for JAMB and WAEC. I designed, built and deployed the entire product solo — backend, frontend, AI integration, payments and DevOps.
The platform includes a 10,000+ question bank across 14 subjects imported from multiple sources, an AI explanation engine powered by GPT-4 that explains every wrong answer in simple English, personalised weekly study plans, mock exams that simulate real JAMB CBT, weak area detection and JAMB syllabus-based topic notes.
Payments are handled via Paystack supporting card, bank transfer and USSD across three subscription plans. The frontend is a PWA built with vanilla JavaScript.
Built with Laravel 11 REST API, OpenAI GPT-4, Paystack, MySQL, vanilla JS, Bootstrap and deployed on Ubuntu VPS with Nginx.

MyCarrier: DevOps & Cloud Transformation for Scalable Logistics SaaS
Preview description:
We helped MyCarrier move toward cloud-ready DevOps: adapted the system for microservices, implemented CI/CD and test automation, moved workloads to Azure, achieved 99.9% availability, decreased update delivery time to minutes.
Full description:
Problem
MyCarrier was growing fast, and the monolithic codebase became harder and more expensive to maintain. It was heavy, resource-consuming, and less suitable for the client’s long-term scaling plans. The team also needed faster delivery processes, but changes in the codebase and cloud migration had to stay unnoticed by users. Their logistics workflows could not be interrupted.
Solution
IT Craft aligned the project infrastructure with a microservices architecture and prepared the system for cloud operation. The team started with a technical audit and developed the migration strategy consisting of 20-28 items. The process was divided into pre-migration, migration, and post-migration phases, thus the product could keep running while infrastructure changed step by step.
The team moved non-critical standalone jobs to the cloud, connected virtual machines to Azure Storage Account, moved logging to MongoDB Atlas, and transferred user data and related processes to the cloud. New app functionality was released as microservices. IT Craft also designed and fine-tuned a CI/CD pipeline, automated infrastructure deployments, and reduced update delivery time through regression test automation.
Results
· Achieved 99.9% system availability.
· Maintained high fault tolerance using three shared clusters.
· Reduced update delivery time from hours to minutes.
· Enabled Sprint focus changes every two weeks based on client priorities.
Tech Stack:
· Azure Cloud
· MongoDB Atlas
· Azure SQL
· Azure App Service
· Azure Functions
· Azure Storage Account
